For these sometimes-difficult areas, Koberstein favors upright plants, or plants that respond well to trimming. "Holmstrup Arborvitae is a narrow, upright evergreen good for tight spaces. I would also recommend using Annabelle hydrangea or Peking cotoneaster (Hedge cotoneaster) for foundation plantings since both shrubs are pretty shade tolerant and the cotoneaster has good fall color," she says. In a shady situation, Koberstein generally advises homeowners to seek out plants that are tolerant of dry shade, since overhangs on homes often create drier conditions below.
